And Now For Something Completely Different…Posted on 9:34 am October 12, 2009 by James Morle
So just a short post today, more of an announcement...
At 11.05am on Wednesday 2nd December, I will co-present a talk at the UKOUG conference with Tanel Poder. OK, so nothing particularly earth-shattering there. However, we've decided to do something a little bit different with the creative process. The talk is entitled "The Oracle Wait Interface Is Useless (sometimes)", and is a subject that both Tanel and I have been working on separately for a little while. The premise is this: The wait interface is great for 'slow' waits, but what about waits that are not instrumented by the wait interface? What about waits that are not waits from Oracle's perspective, such as reading a page of memory? What about pure inefficiency? There is, of course, the concept of DB Time, but it is not currently granular enough.
So, you probably can see the idea behind the presentation: The goal is to present some alternative diagnostic techniques to determine the cause of poor performance. We happen to both have similar ideas on this, and they don't just stop at Oracle.
So here's the new concept, at least for us: We are going to write the content for the presentation as a tag team effort between our two blogs. Airing our dirty laundry in public, so to speak. We think this will give a fairly unique opportunity for public comment before the presentation is actually given!
So, over to Tanel for part one...
